This is worth a listen. It is not a sound bite - maybe 15 minutes - but if you have forgotten what it is like to have a leader who possesses not only great eloquence but also respect for the intelligence and character of his audience, this is a good reminder. You can see why the British people were willing to stick with Churchill despite the set-backs, the screw ups and the eccentricity. It may be my imagination but this talk seems a little more low-key than those of last spring and summer. After the ordeals of the intervening months there is no need for cheerleading. Just a sober situation report with the encouraging belief that with America's backing (which now appears to be forthcoming) the allies will prevail in the end.
I'm not sure about the posting date though. In The Grand Alliance Churchill places it on May 3, the evening preceding his letter to Roosevelt of May 4.
